NASHVILLE, Tenn. -- Astro Cantus is an I-phone app that gives voice to the stars.

The musical app is the brainchild of Rocky Alvey, Director of Vanderbilt’s Dyer Observatory in Nashville.

The application uses sky charts to assign musical values to the stars that are passing overhead at any given moment. At present, musical values are assigned according to the star’s brightness, but Alvey says most any astronomical data could be used.
